Notes
- Set SW1 to BAT when the board is installed. Software will not
initialize Prestoserve unless battery backup is enabled.
- Set SW1 to +5V when the board is removed and cache data does not need
saving.
- Cache is cleared when SW1 is set to +5V for more than five minutes.
- Do NOT accelerate the root file system.
- Install Patch
 101714-01
for Prestoserve 2.4 and 2.4.1, or
103043-08
for Prestoserve 2.4.2.
- The Prestoserve hardware design is not compatible with 64-bit DVMA.
Disable 64-bit DVMA when Prestoserve is used with Ultra 1 Model 170E,
Ultra 2, and SunSwift. Refer to BugID 1224649. Add the following to
/etc/system:
- set fas:fas_enable_sbus64 = 0
- Only 32-bit drivers are provided by the Prestoserve software, so if
you are running Solaris 7, you must boot in 32-bit mode for the
Prestoserve drivers to load.
See SRDB 18572.
